Answer 1

A lot easier solution would be

(UIImage *) modifyImage:(UIImage *)inputImage
{
   UIGraphicsBeginImageContext(inputImage.size);
   [inputImage drawInRect:CGRectMake(0, 0, inputImage.size.width, inputImage.size.height);
   CGContextRef ctx = UIGraphicsGetCurrentContext();
   //Drawing code using above context goes here
   /*
    *
    */
   UIImage *outputImage = UIGraphicsGetImageFromCurrentImageContext();
   UIGraphicsEndImageContext();
   return outputImage;
}
